A kind of buried unpowered sewage disposal device

Technical field

The utility model relates to the treatment unit and the technology of the buried unpowered sewage disposal device and the technology, particularly low-concentration organic waste water in a kind of environmental protection field.

Background technology

Water is Source of life, is unique irreplaceable natural resources on the earth.Along with industrialized process, insufficient water sources, water pollution and water surrounding ecological degeneration have become the restraining factors of social development.Modern sewage disposal technology can be divided into physico-chemical processes and biochemical process two classes by its action principle.Thing is given birth to handle and is comprised sieving, precipitation, come-up, air supporting, filtration and reverse osmosis and neutralization, coagulation, electrolysis, redox, stripping, extraction, absorption and ion-exchange, electrodialysis etc., biochemical treatment then is a metabolism of utilizing microorganism, makes the organic pollution materials that is dissolving, colloidal state in the sewage be converted into stable, harmless material.This conversion process is exactly the biological chemistry treating processes, is called for short the sewage biochemical process.Biochemical treatment can be divided into aerobe and handle and anaerobic biological treatment two big class treatment processs according to microorganism growth to oxygen environment requirement difference.In the practice, often the materialization processing is combined with biochemical treatment, its typical processing core process is " anaerobism+aerobic+filtration ", but in the aerobic treatment stage, all need the power oxygen supply, so just, consumed the energy, increased running cost, brought serial problems such as noise jamming, maintenance of the equipment, other buried unpowered sewage disposal technology or device are because of its anaerobic treatment process sheerly, employed filtrate is pebbles or cinder, exist out water ph value and be acid, problem such as processing efficiency is low, and decontamination effect improving is bad.

Summary of the invention

In order to overcome deficiency and the defective that above-mentioned sewage disposal technology device exists, the utility model adopts " anaerobism, hold concurrently oxygen and filtration " to handle the sewage disposal technology that combines.Purpose is to provide a kind of buried unpowered sewage disposal device and technology, and this device has treatment effect preferably to the organic waste water of lower concentration.This device is applicable to the sanitary sewage disposal of hospital, biotope, factories and miness, enterprises and institutions.

The utility model addresses the above problem and is achieved by the following technical solution: a kind of buried unpowered sewage disposal device.Water-in, water outlet, pump well, equalizing tank, biologic packing material pond, biological filter and natural oxidation pond and disinfection well at existing sewage disposal technology.Be provided with grid at pump well, then be provided with filler in the biologic packing material pond, each pond body also is furnished with inspection window, so that the usefulness of maintenance.The above each processing unit of its constructional feature pond body can be made of one makeup and put and be embedded in undergroundly, to save the area, is provided with supporting base and filtrate and shore pipe in the biological filter, and filtrate is placed on the supporting base, and shore pipe runs through filter material layer and supporting plate.

The selected filtrate of the utility model is a Wingdale, in order to pH value and the filtration in microbe carrier and the adjusting sewage, holds back suspended substance.

Equalizing tank of the present utility model, biologic packing material pond, biological filter, natural oxidation pond and sterilization pool, all there is pipeline to link to each other between them, in the biologic packing material pond, carry out the one-stage hydrolysis acidification, carrying out secondary anaerobic in the biological filter handles, carrying out three grades of double oxygen in oxidation pond handles, in case of necessity, carrying out level Four in sterilization pool disinfects.Make the water outlet allow compliance with emission standards thus.

Each pond body of the utility model is above its liquid level, and Chi Gai bottom surface, the adjacent part of pond body all have pore and communicate, and causes outside the pond after the waste gas that each processing unit produced can be collected in the lump and discharges.

Natural oxidation of the present utility model pond, liquid level is above to be interlinked to the outside with the pond, is provided with biofilter material in the pond, and thickness in order to prolong sewage in this pond residence time, makes the outer oxygen of its natural better cuvette near sewage level, improves purification efficiency.

The utility model has the advantages that to be buried unable waste disposal plant that this has treatment effect preferably to this device to the organic waste water of lower concentration.This device is applicable to the sanitary sewage disposal of hospital, biotope, factories and miness, enterprises and institutions.
